Created empty console application
Implementation of a basic unsupervised clustering algorithm

See
https://github.com/laurita/scluster/blob/master/lib/scluster/clusterer.rb
Working first version of clustered but very very slow

Cannot go above 20 logs.
Added Add method to process an additional log in the clusterer
Differentiated error location/message/stack trace

-> clustering is done only message for now
A few tests on grouping only on stack trace
